BACKGROUND OF THE INVENTION

FIG. 1 illustrates a prior art whirlpool tub system including a tub 12 having a sidewall 14 and a upper deck rail 16′ connected to the sidewall 14. A cold water control valve 18 and an associated handle 20 are mounted to the upper deck rail 16 and a cold water inlet conduit 22 is provided and is connected to the cold water control valve 18. A cold water outlet conduit 24 runs from the cold water control value 18 to a diverter valve 26. A diverter handle knob 28 is connected to the diverter valve 26. A hot water valve 30 and an associated hot water valve handle 31 are also mounted to the upper deck rail 16′. A hot water inlet conduit 32 runs to the hot water valve 30 and a hot water valve outlet 34 runs from the hot water valve 32 to the diverter valve 26. A first diverter valve outlet conduit 36 runs from the diverter valve 26 to a vacuum breaker 38 positioned in an overflow box 40 mounted behind a bathroom wall 42. A vacuum breaker outlet conduit 46 runs from the vacuum breaker 38 to a handheld shower 50. The handheld shower mount 52 having a through hole form therein may be received in a through hole formed in the upper deck rail 16′ to hold the handheld shower 50 in a mounted position. The vacuum breaker outlet conduit 46 includes a flexible portion connected to the handheld shower 50 to allow the handheld shower 50 to be retractably removed from the mount 52 and used by an occupant of the tub 12. A second outlet conduit 53 extends from the diverter valve 26 to a tub spout 55, that is also mounted to the upper deck rail 16′, to allow water to flow into the tub 12 when the diverter valve is moved to change the flow of water from the handheld shower 50 to the tub spout 55. The area under the upper deck rail 16′ in which the water piping or conduits must be connected and soldered specifically less than six inches. As a consequence, it may take a plumber more than six hours to install a whirlpool tub and handheld shower system as described above. Numerous elbows must be soldered together in a very small work area. The more soldered joints there are increase the likelihood of a leak. Furthermore, the use of a vacuum breaker 38 and a drain pipe 44 in an overflow box 40 that is mounted behind the drywall 42 of the bathroom typically limits the installation of this whirlpool tub and handheld shower combination to new home construction. Installing the overflow box 40 after the home has been built requires removal of any title and the drywall. Even more time would be associated with converting an existing installed whirlpool tub to include a handheld shower wherein the overflow box 40 would have to be installed behind an existing building drywall 42.
